correct add 1 to the current size, gpuRange as gpuRange
only specifies the end address of the pool, not the actual
size, which causes alignment issue of all the offsets of
allocated objects. Also, a page was added in the beginning
of the limited range memory pool to avoid the base address
of it to be 0x0 that is interpreted as invalid address by
heap allocator (This makes the size reduced by pageSize)
Internal 32bit allocator is also initialized in proper way
with corrected base address.
v2: added 'givenMemoryManagerLimimedRangeAllocator' unit
test
v3: adjust size to be freed when DrmMemoryManager instance
is destroyed to 4GB
v4: - defined external 32bit allocator for limited Range
allocation case.
- softpinning object on the correct GPU address

- make AllocationData a protected structure
- use AllocationProperties instead of AllocationFlags
- refactor methods: allocateGraphicsMemory64kb, allocateGraphicsMemoryForSVM
- call AllocateGraphicsMemoryInPreferredPool in AllocateGraphicsMemory
where there is no host ptr

pass struct with properties to allocate graphics memory methods:
for protected methods use AllocationData
for public methods use AllocationProperties

- createGraphicsAllocationFromSharedHandle was not threadsafe,
instead of reusing BufferObject for a single handle when
multiple threads were creating memory objects from a single VASurface,
new BO could be created and placed in container with BOs for reuse.
This was leading to errors in ioctl calls.
- add lock for following set of operations:
1. find BufferObject with a given handle in container
2. create shared BO when not found
3. add shared BO to container
prevents creating multiple BOs for a single handle
- replace recursive mutex with regular mutex as mutex shouldn't
be locked recursively
